本文讨论了一个数据隐藏问题,其中一个源图像需要隐藏到另一个主机图像。我们考虑两种情况下,解码器可以访问主机图像(非盲数据隐藏),当解码器不(盲数据隐藏)。我们提出的解决方案结合了完全互补(CC)扩频序列和嵌套标量量化(NSQ)。为了增强安全性,在嵌入之前对源图像进行加密。我们的仿真结果,非盲和盲数据隐藏,与AWGN攻击显示出竞争力的结果。事实上,对于盲数据隐藏,我们的设计优于传统的NSQ系统8 dB。
This paper addresses a data-hiding problem where a source image needs to be hidden into another host image. We consider both cases when the decoder has access to the host image (non-blind data-hiding), and when the decoder does not (blind data-hiding). Our proposed solution combines complete complementary (CC) spreading sequences and nested scalar quantization (NSQ). To enhance security, the source image is encrypted prior to embedding. Our simulation results, for both non-blind and blind data-hiding, with AWGN attacks show competitive results. Indeed, for blind data-hiding, our design outperforms the traditional NSQ system by 8 dB.
